You might also want to check for frequent STP topology changes (TC), typically coming from edge ports that are not configured with RSTP edge, auto-edge or 802.1D portfast.

Such edge ports will trigger a topology change (TC) every time they change their state (up/down).

Even in a otherwise stable switch topology such changes will cause a flush of mac address tables, resulting in temporary unicast flooding.

Together with an incorrectly configured (or broken) bond this could explain what you are seeing.
